Review on GM Genuine Parts Engine Cooling Fan Clutch 15-40133 - Improved SEO-friendly product name by Stephen Parkell

Works as expected. Some people feel embarrassed that they received the wrong order because the part is marked as Behr. This is original equipment. I have tried fan clutches from 3 different brands (1aauto, Haynes, some other Chinese) for 2 years. Nothing worked properly. This is a proper fan clutch that is worth every penny. Don't waste money on other brands. I think there must be some internal patents because others run at much higher RPMs.
